DX Engineering Receiver Guard Electronic RF Limiters
DX Engineering Receiver Guard RG5000HD Electronic RF Limiters are the best choice of inline devices to protect your receiver antenna inputs. The Receiver Guard is a receive antenna input limiter specifically designed to protect a sensitive receiver front-end against high levels of RF and potential damage. At the heart of each Receiver Guard is a highly effective electronic RF limiter covering 500 kHz to 150 MHz with an insertion loss under 0.15 dB up to 50 MHz and under 0.30 dB up to 150 MHz. The multi-stage design includes a gas discharge tube for maximum pulse energy protection. The DXE-RG5000HD rejects 10 watts of catastrophic receive antenna feedline RF while passing a maximum signal of about 87 dB over S-9, which is only 25 mw, a signal level that is well below the point of front end damage. Receiver Guards are a must for multiple radio contesting stations and they provide low-cost front-end "insurance." Use them in these common high-RF situations: - Receive antennas in very close proximity to transmit antennas - Field-day operations with many transmitters in close range - Multi-transmitter contesting sites - Neighboring Amateur and CB operators - Frequent high-power mobile encounters Extensively tested and proven in real-world stations, the Receiver Guard works for all radios and offers the ultimate performance required by the upper tier of transceivers tested to have the best narrow-spaced third-order dynamic range or published RMDR (Reciprocal Mixing Dynamic Range). These are passive electronic limiters, so competitive contesting stations use separate band filters in addition to the Receiver Guard. When there are high levels of RF on your receive antennas, the DX Engineering Receiver Guard generates far less harmonic noise than other limiters on the market, which allows your station to continue to operate safely and competitively. At normal HF signal levels the RG5000HD operates continuously with no effect on the performance of your station while providing the best possible protection for your radio. Here are key Receiver Guard features: * Keeps stray high levels of RF from damaging your receiver input * Ideal for separate 160 and/or 80 meter receive systems with large pulse and RF energy capture area * Uses state of the art components for maximum protection of receivers * Under 6 ns response time * Multi-Stage protection * Very low insertion loss * Uses BNC type connectors to avoid accidental connection to a transmit feedline * Has been developed and tested in world-recognized multi-multi contest station K3LR Specifications - DX Engineering Receiver Guard model DXE-RG-5000HD - Frequency Range: 0.5 through 150 MHz - Insertion Loss: < 0.15 dB up to 50 MHz, < 0.3 dB 50 MHz up to 150 MHz - VSWR: < 1.2:1 - Maximum Output Level at 10 W input: +14 dBm (0.025 W) - Maximum Power Handling: 10 W CCS (Continuous Commercial Service) - Device Impedance: 50 to 75 ohms, unbalanced - Connectors, Input and Output: BNC female Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information.

They work as a high impedance buffer between a short antenna element of 6 to 24 feet and an economical 75 ohm feedline. The AVA-3 and a short element are intended to be mounted on a ground rod at ground level in a clear area away from all metal, towers and other antennas. The gain adjustable AVA-3 is the sole upgrade and drop-in replacement for all discontinued receive array element amplifiers including Hi-Z Antennas AMP, PLUS6-AMP, AMP-V2 and AMP-PLUS-V2 as well as DXE-AVA-2 and AVA-1. The DXE-AVA-3 Active Matching Unit is the heart of the new line of DX Engineering Receive Short Element Active Vertical Antennas, DXE-RSEAV-1. Compared to large antennas, this amplified short element method dramatically improves signal-to-noise performance for excellent VLF, LF and HF weak signal reception. Click or tap the title of the listed item for an overview - a complete description, Specifications, Required and Suggested Parts. Links to instruction manuals and charts appear in Documentation. The AVA-3 Active Matching Unit provides these features and benefits: • Ultimate frequency coverage of 40 kHz* to 30 MHz for VLF through HF (including the 2200m and 630m Amateur bands) • High Third Order Intercept (TOI) Performance +39dBm for superior strong signal handling equal to top transceivers • Consistent unit to unit gain for greatly improved array performance • Virtually Flat Gain (+/-0.4 dBm) across the entire frequency range • Internally settable gain (default -6, 0, or +6 dBm) for different ambient noise locations and element sizes • Direct DC via second F connector – internal settable choice for separate DC and RF coaxial cables for best performance, or standard Bias Tee DC on the RF coax • Each DXE-AVA-3 Active Matching Unit operates on 12 -15 VDC at 25mA • Element is grounded when power is removed • 75 ohm F connectors support field serviceable RG-6 Quad Shield suitable up to 1,000 feet for VLF through HF *Frequency coverage below 200 kHz requires Direct DC on a separate DC only coaxial cable. Please Note: To achieve the expected reception pattern, multi-element phased arrays depend upon identical gain and phase response from each element. Every individual element amplifier, its grounding, and even its feedline characteristics and length, must be identical to the others in the array. Therefore, when unrepairable failures occur, it is essential to replace and upgrade all the element amplifiers in the array with fully compatible DXE-AVA-3 units.

COMPACtenna LMR-I Land Mobile Radio Antenna
The COMPACtenna LMR-I Land Mobile Radio Antenna is a high performance, low-profile mobile antenna designed for government and commercial applications, with coverage of three optimized frequency ranges: -- High VHF 136-174 MHz -- Low UHF 378-512 MHz -- High UHF 750-960 MHz COMPACtenna LMR-I works for analog and digital operation modes for Police, Fire, Sheriff, Emergency Medical, State Highway Patrol, Homeland Security, U.S. Federal, Military and Business-Commercial applications. The LMR-I is an attractive 9 in. tall, cylindrical radome-style antenna with a reliable leaf spring style NMO mount base for standard center-stud style NMO mobile mounts. It may be used for Vehicular or Base Station – Repeater operations by adding an optional CompacCounterpoise. COMPACtenna LMR-I provides high performance using a unique Electric-Magnetic Field Diversity design. Superior Omni-directional coverage is achieved far beyond what would be expected for the antenna size. The multi-faceted geometric design of the antenna includes "extended flat monofilar spiral Tesla-like coils" that serve as the LCR matching system, resonating as an integral part of the signal field generation. No external or internal electronic lossy matching components are used. This design establishes diverse electromagnetic fields, resulting in signal stability and performance greater than expected in NLOS (Non-Line-Of-Sight) environments, reducing the effects of ionospheric polarization shifts. COMPACtenna LMR-I Specifications: * Frequency Coverage: 136-174 MHz, 378-512 MHz, 750-960 MHz * Power Rating: 100 W VHF; 75 W UHF * Duty Cycle, Max. Power: 1-minute transmit limit in a 2-minute period * Repeater Operation: 30W maximum at the antenna * Maximum Ambient Temperature: 130 degrees F (hotter conditions, sun exposure, limited air flow reduces duty cycle) * Gain: 3 dBi, nominal (performance greater than predicted based on gain alone in Non-Line-Of-Sight environments * SWR, nominal: < 2.1:1 140-162 MHz, 400-500 MHz, 750-960 MHz; <2.5:1 136-140 MHz, 162-174 MHz, 378-400 MHz, 500-512 MHz. Best SWR on VHF frequencies when LMR-I antenna is mounted on an upper corner of a vehicle, NOT center mount. Flat style magnetic mounts provide the best SWR results. SWR varies with size and shape of the vehicle.
